Wool dryer balls are practically magic, these reusable gems allow you to skip the wasteful and expensive dryer sheet, but add all them same benefits. The wool dryer balls come with natural New Zeland wool, no chemicals, no filler, and no dyeing, which makes them safe for you, your family, and those with sensitive skin. And lets not forget, they can shorten drying times (which saves money), and can be used over, and over again.
